AVERY VAN \VIE, OF INDIANAPOLIS, INDIANA.

SHUTTER- FASTENER.

SPECIFICATION forming part of Letters Patent No. 313,261, dated March 3, 1885.

Application filed April 10, 1884. (No model.) I

To ctZZ whom it may concern Be it known that I, AVERY VAN Win, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in BlindF-asteners, of which the following is a specification.

The object of my said invention is to produce a secure fastening whereby blinds may be secured together; and it consists of an appropriate housing secured to each blind, a catch-bar pivoted to one housing, and a catch within the other adapted to engage with said bar, and a key for disengaging said catch from said catch-bar, as will be presently more fully described.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a view of the inside of a window having blinds provided with my in vention, the lower sash of the window being raised to show the location of the fastening; Fig. 2, an elevation of the fastening and the portion of the blinds to which it is attached on an enlarged scale, the two positions of the catch-bar being shown by means of dotted lines; Fig. 3, a horizontal section on the dotted line z z,- Fig. 4, a vertical section on the dotted line y 3 Fig. 5, a vertical section on the dotted line x m; Fig. 6, a view of the key, and Fig. 7 a plan view of the catch-bar separately.

In said drawings, the portions marked A 13 represent the blinds; O O, the housings forming part of my improved fastening; D, the catch-bar thereof; E, the catch for said bar, and F the key for unlocking the device.

The blinds A B are the ordinary outside window-blinds, and need no description, except incidentally, in describing the fastening.

The fastening, as before indicated, consists of the two housings O O and the catch-bar D and the catch E therefor. The housing 0 is secured to the blind A, as shown, and has the catch-bar D pivoted therein. The housing 0 is in like manner secured to the blind B, and has the catch E secured therein. As will be seen, these housings are so constructed that when placed with their closed ends up, as shown in the drawings, there can be no snow or rain get inside, as the upper ends form a perfect roof. However, while this arrangement is preferable and quite desirable, I do not desire to confine myself thereto, as the fastening will hold the blinds just as securely when the ends are reversed, as will be readily understood.

The catch-bar D is of sufficient size to hold the blinds securely when locked. It is pivoted in the casing C, as before stated, on the pivot d, it being rigidly mounted on said pivot, and the ends of said pivot being journaled in suitable bearings in said casing. A knob or handle, (1, is provided on the outer end of said pivot, by which it is rotated, and the catch-bar thus thrown up into engagement with the catch E in the casing C when locked, and withdrawn therefrom when unlocked. A notch, d", is provided in the face of said catchbar at its other end, with which the catch E engages. A recess, d, is also formed by the side of said notch for the purpose of admitting the key F, the end of which rests in said recess when inserted in the key-hole. A spring, (1*, may be placed between the casing and the end ofthe bar, which bears down upon said bar andprevents it from rattling or be coming loose.

The catch E is a spring-catch, secured at one end in the top ofthe casing 0', and adapted to spring in toward the blind. The catch is formed near the center of the casing in which is formed the key-hole, and has a hole corresponding to the key-hole also extending ent-ly described.

appropriate thumb-pieces on one end, and lugs f extending out from two sides of the key end. It may be of any length desired. The lugs are preferably curved, as shown, and the key-holes are correspondingly curved.

. The operation of myinvention is as follows: The parts being in position for use, as shown in Figs. 1 and 2, and it being desired to lock the blinds, the catch-bar D is thrown up into the housing G,when the catch E engages with the notch (l in the end of said bar automatically. key F is inserted in the key-hole until the lugs are below the catch. It is then turned about one-fourth around, bringing said lugs under said catch, which is then disengaged from the notch in the catch-bar by simply through it, for the purpose which will be pres- The key F is usually a straight rod, with It being desired to unlock them, the

ICO

pulling outward on the key, which pulls the catch out of the notch, as will be readily understood. The knob d is used in turning the catch-bar into and out of the casing O, as before described.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is Y 1. The combination, in a blind-fastening, of a housing attached to each blind, a catch-bar, D, mounted on the pivot-sl1aft d in one housing, and provided with a notch inits free end, and a spring-catch, E, secured in the other housing, with which the catch-bar, when brought into contact therewith, will engage, substantially as set forth.

2. The combination, in a blind-fastening, of a housing attached to each blind, a catch-bar pivoted in one housing and adapted to swing into engagement with the other, a spring catch in the other housing, with which said catch-bar is adapted to engage, said housing and said spring each having a key-hole extending through them, and a key adapted to pass down through said key-holes and engage with and raise said spring-catch, substantially as set forth.

3. The combination, in ablind-fastening, of a housing attached to each blind, a catch-bar mounted on a pivot, 01, in one of said housings, a spring, d interposed between said bar and said housing for engaging with and holding said catclrbar, and a key for disengaging said catch from said catch-bar, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 15th day ofApril, A. D. 1884.
